JBL Amp vs JL Amp

And now, after having done a little research on the Basic Car Audio Electronics website and a few other places, here is what I have found:

Using values of 4AWG wire, 20 ft. run of wire, at 1000W, with 75% eff. (for a class D amp), and a system voltage of 13.8, I got a voltage drop of .483 volts. IF I've entered the info correctly and IF I understand this calculator to depict what ragoal12 is getting at, that seems rather negligible to me. Even using a value of 12 volts for system voltage, it gives a message that says, "There will be more than a 1/2 volt drop in your power wire at full power. Use a larger gauge wire." The 1000/1 specifically asks that the user use 4AWG wire and a 100A fuse on the line. Using a shorter wire run also reduces the voltage drop.

So, can someone enlighten me some more? I'm sure I'm missing something here...

paradigm does that have anything to do with the question that was originally asked??? cause ur attempt at flaming me isn't working...  chill out man.. i was simply saying that both voltage hungry and power hungry r commonly referred to as the same thing...

now u say that u have 1000/1 do u run 4 AWG wire? because the systems that i've dealt with originally had it and there was considerable amout more voltage drop... like 2 or 3 volts.... and its occured in more than one system

Maybe in your neck of the woods this is true. However, I've never heard of this from anyone else on this board or otherwise, and I would hazard a guess as to say that voltage hungry and power hungry are, in fact, NOT the same thing. Again, unless someone can tell me (and prove) otherwise, I will accept this as fact. I found this on another forum, "Remember that power is voltage x amperage, and the amperage depends on the impedance. If the impedance is high, it takes more voltage to double the power than if the impedance is low, because less current flows at low impedance with the same voltage." Just thought I'd throw that in there for whatever reason.

Yes, I do have a 1000/1 (as shown in my sig), and yes, I do run a 4AWG wire from the distro block to the amp. My main wire is 1/0AWG. Probably overkill, but it does the trick and I know that I am better safe than sorry. And as I pointed out, if you calculate voltage drop, the results are negligible. Are these real world numbers? Probably not, since other factors are not accounted for in the calculations. But the audio system, by itself, should match pretty close to the calcs.

Alternators are rated in amperes. When someone asks the question whether they need a high output alternator, almost every single time, the answer will be based upon how many amps are required to operate the system adequately and what amp rating the alt should have. NOT on what the voltage drop will be or how voltage hungry the system is.

This may, in fact, be a good side discussion to the original poster's question, as he may need to account for some of these things. A little extra knowledge never hurts . But I caution that knowledge presented should be correct, and if not, someone should have the courage to set things right. And there are a number of us that will do just that.

My guess is you don't like to be corrected. Sorry, I just was trying to understand what you were saying. I'm calm, my heart rate hasn't risen, and the world is still here, with me and you in it. Let's try to get along, shall we?

Just for the sake of public service, what follows is basically all that this thread's author is asking.  Maybe it can get back on track now.

Now I may be mistaken, but I don't think he meant an in-depth review of Ohm's Law and such related matters when he asked "Gimme some good feedback guys on watcha think please."

Not back on topic!!! Please!!!!

I only have experience with the JL Audio 1000/1, so I can only give my opinion on it, along with what I have already posted. It is a fantastic amp, but it will cost you quite a bit, even if you manage to find it at a discount from the Internet or from a dealer. I paid about $750 new from an authorized dealer. I have no complaints - it is probably more amp (other than wattage) than I will ever need.
